"Stroke" is the name of Chinese medicine, and it is also the general name of acute cerebrovascular disease. Traditional Chinese medicine believes that there are six evils, namely "wind, cold, heat, dampness, dryness and fire", also known as "six evils". Among them, diseases caused by internal wind, that is, many types belong to stroke.
Stroke is characterized by sudden fainting, unconsciousness, mouth-eye deviation, language impairment and hemiplegia. Cerebral hemorrhage, subarachnoid hemorrhage, cerebral infarction, cerebral thrombosis and transient ischemic attack referred to by modern western medicine also belong to the category of stroke. Because of its rapid and fierce onset, it is similar to the characteristics of wind in nature, so the word "stroke" first appeared in Huangdi Neijing, a medical monograph in China more than 2000 years ago. Because of its sudden onset, it is also called stroke or cerebrovascular accident.
The origin of stroke is hypertension and cerebral arteriosclerosis. When atherosclerosis occurs in the cerebral vascular wall, the vascular lumen narrows or forms a dissecting aneurysm. Under the influence of emotional excitement, mental stress or overexertion, high blood pressure and other incentives, blood vessels are ruptured or blocked, which causes cerebral blood circulation disorder, causes pathological changes such as ischemia and edema of some brain tissues, leads to neurological dysfunction, and thus a series of stroke symptoms appear.
The most common symptom of stroke is that patients have different degrees of language, motor and sensory dysfunction. Among them, motor dysfunction is called hemiplegia in Chinese medicine, but hemiplegia caused by brain cyst, brain parasitic disease and brain abscess does not belong to the category of stroke.
What are the names of strokes?
There are many names of stroke. With the continuous understanding of the disease in traditional medicine and modern medicine, there are even many different names. The record of stroke was first seen in Huangdi Neijing more than 2000 years ago. Su Wen ",which describes this disease as" the blow of the servant is too dry ",that is, a limb suddenly cannot move autonomously. Zhang Zhongjing officially named the disease "stroke" in the Eastern Han Dynasty, which can be divided into true stroke and quasi-stroke. These medical works fully show that ancient physicians in China had a thorough study of stroke. Some scholars call it "cerebrovascular accident" and "cerebral hemorrhage". Japanese scholars call this disease "stroke" according to China traditional medicine. Folk call the disease "hemiplegia", and Western medicine uses the abbreviation CVD according to the English letters of the disease.
The appellations of the above names all belong to the category of stroke, and patients must not be confused by many appellations, resulting in missed diagnosis or misdiagnosis.
How many kinds of strokes are there? What diseases are included?
Stroke is a general term for acute cerebrovascular diseases. According to the different nature of cerebrovascular damage, stroke generally includes two types. One is ischemic stroke, which mainly includes cerebral infarction and transient ischemic attack (mini stroke). Cerebral infarction is divided into cerebral thrombosis and cerebral embolism.
Cerebral infarction: refers to local brain tissue necrosis caused by insufficient blood supply, also known as cerebral infarction. Cerebral thrombosis: refers to the pathological changes of the cerebral artery wall, which is based on atherosclerosis. Slow blood flow and increased blood viscosity cause obvious stenosis or occlusion of the arterial lumen, leading to infarction in the corresponding parts of the brain.
Cerebral embolism: The abnormal substance (fat embolus) in the body flows into the cerebral artery or the carotid artery supplying the brain along the blood circulation, resulting in blood flow obstruction or infarction. The other is hemorrhagic stroke, which mainly includes cerebral hemorrhage and subarachnoid hemorrhage.
Cerebral hemorrhage: refers to cerebral parenchymal hemorrhage, 80% in the cerebral hemisphere and 20% in the brain stem or cerebellum.
Subarachnoid hemorrhage: Blood flows from a ruptured artery or vein in the brain, such as a subarachnoid space.
According to statistics, patients with cerebral infarction account for 47%-60% of the total number of stroke patients in China. Patients with cerebral hemorrhage account for about 40% of the total number of stroke patients.
